Finally, a brand new section explains how to dial in rich, analog saturation using the Heat feature.
The Positive Grid Reactor Tone Guide is now live with 50+ pages of content covering everything you need to master the Reactor.
With a background in computer engineering and digital marketing, I have always looked at gear through an analytical lens. When I first started using Positive Grid Amps, I loved the potential, but I found the lack of clear documentation frustrating. I spent months "reverse-engineering" the models and controls because I wanted a manual that simply didn't exist.
I created this guide to help fellow Reactor owners skip the "trial and error" phase and get straight to the music. My goal is to provide the structured, logical reference we need to master this ecosystem.
